Steam Pressure Reducing Valve Manufacturer in China
The steam pressure reducing valve is suitable for the steam medium pipeline, and by regulating it, the inlet pressure will be reduced to a certain required outlet pressure. When the inlet pressure and flow rate change, the medium itself can automatically maintain the outlet pressure within a certain range, but the difference between the inlet pressure and outlet pressure must be ≥ 0.2Mpa / cm2.

Various Types of Our Steam Pressure Reducing Valve
The cage type single seat control valve is a high-performance single seat regulating valve, which is suitable for high pressure differences and flash vaporization and cavitation. The strong valve cage is protected from damage by flash vaporization and cavitation.
The feed water rotary control valve and the valve disc both have throttling holes, and the flow area is changed by rotating the valve disc in the valve seat to adjust the flow rate. It is used to regulate the flow in the water supply pipeline. It can also be used in the oil pipeline.

Steam Pressure Reducing Valve Application Scenarios
This is suitable for steam medium pipelines, and by adjusting it, the inlet pressure will be reduced to a certain outlet pressure. When the inlet pressure and flow rate change, the outlet pressure can be automatically kept within a certain range by the energy of the medium itself.
Steam pressure reducing valve is suitable for steam pipelines with large flow, large flow change, and large change in inlet pressure.
A steam pressure reducing valve is that when the pressure sensor detects that the valve pressure indicator has increased, the valve opening of the pressure reducing valve is reduced.

Testimonial
This steam pressure reducing valve is easy to install, responds quickly, and can be precisely adjusted even when the flow changes greatly. The material is corrosion-resistant. It has been running for more than half a year with zero failures, greatly reducing maintenance costs, and is very reliable.
EngineerAmericaAfter using this steam pressure reducing valve for half a year, the energy-saving effect is remarkable. The valve body structure is compact, saving pipe space, and the cost-effectiveness is high.
EngineerSaudi Arabia
This steam pressure reducing valve is a pilot-operated piston-type pressure reducing valve, composed of a valve seat, a main valve disc, a piston, a spring, and other parts.
The material of this steam reduction valve is WCB and so on.
Product Installation of Steam Pressure Reducing Valve
The steam pressure reducing valve is equipped with adjustable springs at the factory, and users can choose to install it according to the desired outlet pressure value.
Before installing the steam pressure reducing valve, the pipeline system must be flushed and cleaned to prevent impurities such as welding slag and oxide scale from entering the valve and affecting the valve
The door works normally. Steam pressure reducing valve should be installed in a place that is convenient for operation and maintenance, and it must be installed vertically in a horizontal pipeline. It is necessary to pay attention to the direction of the flow of the fluid in the pipeline to be consistent with the direction of the arrow on the valve body, and do not install it in reverse.
When installing and using the steam pressure reducing valve, the stop valve on the bypass pipe should be opened to clear the condensate and steam-water mixture in the pipe.
In order to prevent the water hammer phenomenon caused by the opening of the pressure relief valve from causing damage to the pressure relief valve, if there is no abnormal phenomenon, slowly rotate the adjusting screw in a clockwise direction and adjust the outlet pressure to the desired pressure (based on the gauge pressure after the valve). After adjustment, tighten the locking nut and screw on the protective cover.
A filter should be installed in front of the steam pressure reducing valve to prevent impurities in the medium from entering the pressure reducing device and affecting its performance.
There are two straight pipes before and after the steam pressure reducing valve, the length of the straight pipe before the valve is about 600mm, and the length of the straight pipe after the valve is about 1000mm.
- The steam pressure reducing valve of this product must be installed strictly according to the installation drawing, and any installation pipeline accessories shall not be changed or missing.
- Before using the steam pressure reducing valve, the valve body must be cleaned before installing the new pipeline. Wash away the dirt in the pipes to prevent it from entering. The valve body cavity is blocked, leading to faults and other phenomena.
- If the steam pressure reducing valve cannot reduce the pressure after the initial installation, you can reinstall the spring cover and use it again.
After using the steam pressure reducing valve for a period of time, if the product fails, you can disassemble the upper and lower valve covers, clean the water scale of all parts, and then reassemble and use again. However, care must be taken when handling to prevent any collisions or scratches, and the valve body and valve cover should not be installed upside down.
The steam pressure reducing valve may loosen the secondary valve sealing ring due to repeated expansion and contraction over a long period of intermittent use. If the auxiliary valve sealing ring and the lower sealing surface of the copper gasket leak air, you can remove the spring cover and tighten it.
